The arithmetic
What the monthly payment actually is
Everyone in this category promises a low monthly payment. Almost nobody prints one.
Run your own numbers below, then read what each extra year of term costs in interest.
Estimated monthly payment — Over 60 months, delivery and installation included.
- Due at signing—
- Amount financed—
- Total of payments—
- Interest over the term—
- First-year tax saving (Section 179)—
- Sessions a month that cover the payment—

Illustrative arithmetic, not an offer of credit. Financing is provided by third-party lenders who set the rate, term, and approval. Tax figures assume the equipment qualifies and your business has enough taxable income; confirm with a licensed tax professional.
The Section 179 line assumes a business purchase, that the equipment qualifies, and that
the business has enough taxable income to absorb the deduction. Set the tax rate to 0% for
a personal purchase. Financing is provided by third-party lenders and nothing here is an
offer of credit.
The table below is the same arithmetic at a fixed illustrative rate, so the only
variable is the term. It is worth reading as a whole rather than looking up one cell,
because the shape of it is the actual lesson: the payment falls steeply as the term
stretches, and the total does the opposite.
| Chamber | Price | 24 mo | 36 mo | 48 mo | 60 mo | 72 mo |
| S1 | $15,000 | $691 | $483 | $380 | $318 | $277 |
| L1 | $49,000 | $2,259 | $1,579 | $1,240 | $1,039 | $905 |
| T2 | $125,000 | $5,762 | $4,028 | $3,164 | $2,650 | $2,309 |
| X | $110,000 | $5,071 | $3,544 | $2,785 | $2,332 | $2,032 |
| T4 | $169,000 | $7,791 | $5,445 | $4,278 | $3,582 | $3,122 |
Monthly payment on the full purchase price, nothing down, at an
illustrative 9.9% annual rate, straight amortisation, no fees. Prices are
our current list prices from the chamber range. Your rate will
differ.
Now the same loans priced in interest rather than in monthlies. Stretching the
$49,000 hard-shell from 36 months to 72 drops the payment from
$1,579 to $905, a 43% cut that feels like a discount
and costs $8,344 more in interest. On the four-seat chamber the same
move costs $28,781 extra, which is close to twice the price of the
entry soft-shell chamber, spent on time.
| Total interest paid | 24 mo | 36 mo | 48 mo | 60 mo | 72 mo |
| S1 | $1,596 | $2,399 | $3,227 | $4,078 | $4,953 |
| L1 | $5,212 | $7,837 | $10,540 | $13,322 | $16,181 |
| T2 | $13,297 | $19,991 | $26,887 | $33,984 | $41,279 |
| X | $11,701 | $17,592 | $23,661 | $29,906 | $36,326 |
| T4 | $17,977 | $27,028 | $36,352 | $45,946 | $55,809 |
Same illustrative 9.9%. Read alongside the payment table: the pair of them is the
trade-off that a single monthly figure hides.
The rate matters less than most buyers assume and the term matters more, but the rate is
not nothing. Held at one chamber and one term, here is what the underwriter's decision
is worth. The gap between a promotional window and a weak-credit approval on the same
$49,000 chamber is $25,657.
| Annual rate, $49,000 over 60 months | Monthly | Total paid | Interest |
| 0% (promotional window) | $817 | $49,000 | None |
| 5.95% | $946 | $56,770 | $7,770 |
| 7.9% | $991 | $59,472 | $10,472 |
| 9.9% | $1,039 | $62,322 | $13,322 |
| 12% | $1,090 | $65,399 | $16,399 |
| 18% | $1,244 | $74,657 | $25,657 |
Rates chosen from what programmes in this category publish: 0% promotional windows, a
5.95% personal-loan floor, a 7.9% post-promotional starting rate, and an 18% weak-credit
approval. The 9.9% row is the illustration used elsewhere on this page.
What you are financing is the invoice, and the invoice is the whole job
The amount financed above is the chamber price, because there is nothing else to fund.
White-glove delivery, installation, calibration and same-day team training are
included in every Superhuman hard-shell, and the chambers need no plumbing, no
special circuit, and no construction. That matters more in a financing conversation than
a purchasing one: equipment bought through a distributor is routinely financed at the
equipment price and then followed by a freight and install bill that the loan does not
cover. The cost guide lists what is included, and the
cost calculator adds the running cost after delivery.
